Pain, swelling, or bruising at the injection site, headache or flu-like symptoms, droopy eyelids or crooked eyebrows, crooked smile or drooling, watery or dry eyes, and infection at the injection site are some of the most common risks associated with Botox Cosmetic. These reactions usually occur if the injection temporarily injures a blood vessel. Injection site reactions usually occur soon after treatment and should go away on their own. It is important to note that because this medication is given to the site of the condition, most side effects occur near the injection site.
This may include redness, bruising, infection, and pain. This is not a common occurrence but it is possible for those who start Botox treatment too early, such as in their early 20s, to be at risk of suffering this side effect. Additionally, this risk increases if Botox Cosmetic is injected into areas of the body that are not recommended or approved by the FDA. To reduce the risk of serious problems and ensure safety, it is important to only receive Botox Cosmetic at a licensed clinic and by a trained medical provider. Some researchers speculate that cosmetic applications may carry fewer risks than therapeutic Botox injections because the doses are usually much smaller.
